Aug 25 PATCH SHIPPED — CVE-2026-73269 (Red Hat multicluster engine for Kubernetes 2.10). Fixed in multicluster engine for Kubernetes 2.10 1787201612.
Description
A flaw was found in the cluster-curator-controller component. A local user, by creating a ClusterCurator resource with a specific naming convention, can trigger the creation of a cluster-scoped ClusterRoleBinding. This allows the user to escalate their privileges from namespace-local access to cluster-wide control. This privilege escalation grants broad permissions, including the ability to access and manipulate secrets, manage cluster actions, and delete hosted clusters or node pools.
